In this paper, we use a phenomenological approach to compare the unusual ways in which language can be experienced by individuals with schizophrenia or severe mood disorders, specifically mania and melancholia. Our discussion follows a tripartite/dialectical format: first we describe traditionally observed distinctions ; then we consider some apparent similarities in the experience of language in these conditions. Finally, we explore more subtle, qualitative differences. These involve: 1, interpersonal orientation, 2, forms of attention and context-relevance, 3, underlying mutations of experience, (...) and 4, meta-attitudes toward language. Such distinctions appear to reflect significant differences in underlying forms of subjectivity; they are broadly consistent with work in phenomenological psychopathology on other aspects of experience, including body, self, and social world. An understanding of such distinctions may assist with difficult cases of differential diagnosis, while also contributing to a better understanding of suffering persons and of psychological factors underlying their disorders.
